Acceleration at start?

Hello everyone,

Thats probably a noob's question, but anyway...

I tried online racing this weekend, and it seems i have a problem with a proper start. My car always accelerates slower at the beginning of the race than others... PP are maxed out to the limit (and all my cars are tuned to the nuts).. tried on many cars.. always the same problem...slower start...
Even when im geting 1st place in grid (for the best lap time), im ending up No16 at the end of 10th second of the race.

Is there any special technique for proper start?
I'm Driving with all helps off exept ABS set to 1. Usually Auto transmission, but if better start requires MT i will switch... will Traction control help? Should it be on when possible?
 
Manual will enable you to start faster, Traction Control can also help in certain cars.
 
Just like a real car its about the rpm at the start in relation to how the car is geared and how much traction you have. I'd assume you're just flooring it and letting it bounce off the rev limiter as the countdown goes? Try holding the throttle at various RPM points (GT5 seems to like it about 2/3rds of the way up the tachometer) and floor it as the start is signaled, not before, or it will either spin the tires excessively or bog down and accelerate slowly. I've found in some of the higher horsepower RWD setups you can launch in 2nd gear quite effectively as well. Modulate the throttle as necessary as well; you want just a very slight bit of wheel spin.

Trial and error my friend, trial and error...

Isn't it car dependent though regarding standing starts? Some cars in the license tests do better when mashing the throttle while others do better when feathering it before the countdown ends and then starting in their "sweet spot" (~4000-6000 RPM).
 
Use grippier tyres if you haven't already.

Also start in second gear if you are experiencing too much wheel spin in first. If you don't want to do that, you can also set your gear ratios so that they are longer, giving you more traction.
TCS on 1 helps on some cars, it acts somewhat like launch control, which is a system that prevents wheelspin when starting.
 
Adjust your transmission: a lower top speed will give your car a faster acceleration (not necessarily faster than others).
What is the power to weight ratio compared to those of others you face. Have you compared your start to that of another driving the same car?
You say that you have tried many cars and experienced the same thing: did you also tune them all (height, springs, toe, camber, etc)? Perhaps the way you tune your car (e.g. too low and springs too hard) the transfer of power is not efficient.
 
I am known for rocket starts and here's a few things I do.

1. 4wd cars...always faster at the start especially in the higher horsepower cars. On some tracks, like Cote' D'Azur, races can be won or lost in the first corner and 4wd certainly can help with that.

2. 2nd and 3rd gear starts...once you get up over roughly 500 hp, and it's different for every car, you can try second gear starts which help dramatically. Less wheelspin, more traction, one less shift. As you do your qualifying lap online, one you pass the start finish, hit the brakes, get out of the way of oncoming cars, and practice your starts in 1st, 2nd or 3rd gear. I discovered this early on in the game and for a time, I blew everyone away at the start. Not so much anymore as it seems people are catching on...lol.

3. Gearing. I change the gearing of all my cars. This isn't according to the book but to me all first gears and most seconds are way too short and completely unusable when racing. I dial them all the way to the left, and the same with second gear and then make smaller adjustments to the left with 3, 4, 5. This brings your usable gears much closer together in the power band and makes second gear usable on some tight corners on some tracks. It also helps with first gear starts as you'll have less wheelspin and more speed before you have to shift into second and third.

I was using RKM Motorsport’s R34 Black Edition
https://www.gtplanet.net/forum/showthread.php?t=136731&page=4

was racing against similar cars or even more weak ones...
i was also driving Mclaren F1 against some subaru impreza on NUR track.. (both limited to 600PP ... or 500... cant remember)

In addition to all the above, it could also have something to do with you installing the high rpm turbo when tuning, it tends to halt your start in favor of better engine performance when moving into the higher rpm ranges. At least that's what I've experienced...
 
If it's possible to start in 2nd do that it cuts out the time it takes to change from 1st to 2nd which I know isn't much but every little helps lol
 
Spin said that Gt likes the rpm 2/3rds of the way up, but for me it always works if the on screen indicator shows 2/3rds full. Of course in GT its bouncing of the rev limiter at about half throttle, but it still works like it does in real life with the exception of the rev limiter kicking in at half throttle.👍
 
Does anyone recall the rumour going around back in the days of GT3 (or was it 4?) about acceleration off the line? Basically, if you kept your thumb on "X" during the countdown, you'd be away slower. The (rumoured) trick was to keep thumb down, then just as the timer switched from 2 to 1, let go, and blip again.

I was never sure if it worked or not!!
 
I find this works -

1. When you start just hold down the throttle into the red. Watch to see where the needle on the rev counter drops down to before coming back up again.
2. Next time you start hold the revs at the point to which you observed in step one.

This should help a little as there will be no drop in revs because you will be starting with the optimum amount and not experience the drop due to lack of momentum.

Hope this helps.

This one I have not tried...can't wait to try it.

No matter how good I get there is always someone online in the same car as me that blows me away off the line. I don't know what they do but the difference is huge. Your only hope then is that they make a mistake but I find that the people good enough to start like that don't make many mistakes later in the race....which means if they take you off the start = race over.

Good question op.
